In April 2017, Mitchell Services announced a material underground contract with BHP at its Olympic Dam mine. Following a successful mobilisation and strong drilling performance to date, the contractor has now entered into a formal variation to extend the contract tenure and materially increase the scope of work.

Under the varied terms, Mitchell Services will provide up to seven underground rigs and will play an integral part in BHP's plans to expand into the high-grade southern area of the mine as part of a broader growth strategy at Olympic Dam. The variation has also resulted in the expiry date extending by a further 12 months to April 2019, with further extension options available.

Mitchell CEO Andrew Elf commented: "I am extremely proud that the company was offered this extension and scope increase. It demonstrates our ability to execute on a safe, efficient mobilisation process and our ability to match the high standards of Tier 1 mining clients such as BHP through safe and productive drilling."
